SpringMvc 第一章：Eclipse用Maven搭建SSM框架并部署到Tomcat7
一 创建项目
创建SSM项目–>选择Maven Project，然后Next
设置项目路径，然后Next
选择项目类型 选择Artifact Id为maven-archetype-webapp，然后Next
设置名称，然后Finish
完成后项目结构，此处报错正常，因为没有导入包
项目结构并不完整，完整就忽略，右键项目->Source Folder创建目录
src/main/resources
src/main/java
src/test/resources
src/test/java若无法创建目录，是因为目录路径存在，只需要在对应目录下右键->Folder创建相应目录就可以
7. 完成后结构如下
8. 简单的创建几个包，可根据实际和个人爱好创建
src/main/java 目录下如下图
9. 在src/mian/webapp/WEB-INF下创建 jsps 目录，如下图
二 导入包，并配置pom.xml
先引入以下几种核心包：
spring核心包
mybatis核心包
spring-mybatis整合包
MySQL连接包
jstl标签类
日志包
json解析包pom.xml文件如下

project>三 配置整合
在src/main/resources目录下创建配置文件如下
log4j.properties 文件如下
#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/test.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c]%m%n jdbc.properties 文件如下
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1/test
username=root
password=root
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000spring-mybatis.xml文件如下

web-app> 此时若启动项目会报一个找不到位置的错误，因为我们配置了mybatis配置文件的路径，但却没有这个文件
解决方法如下：
在com.test.mybatis包中新建mybatis-config.xml文件
mybatis-config.xml 文件如下
<configuration>
<settings>
<setting name="cacheEnabled" value="true" />
<setting name="lazyLoadingEnabled" value="false" />
<setting name="multipleResultSetsEnabled" value="true" />
<setting name="useColumnLabel" value="true" />
<setting name="useGeneratedKeys" value="false" />
<setting name="defaultExecutorType" value="SIMPLE" />
<setting name="defaultStatementTimeout" value="25000" />
settings>
configuration>目录如下图
此时就可以删除这个包下的占位文件了
四 配置Tomcat7并发布项目
打开Window->preferences 选择service ->Runtime Environments
点击add
选择tomcat 7.0，然后Next下一步
选择本地jdk，然后Finish，将项目添加进tomcat并启动
出现这些的时候表示成功启动进入浏览器运行项目
项目成功配置完成
